Processor compatability

Not a chance. You cant swap an AMD for an intel, the sockets are physically incompatible, and you wouldnt be able to purchase any processor new today that would fit into a pentium III socket, especially not an older laptop one like that. A cheap netbook would greatly out perform that system though for only a couple hundred if you dont have the funds to buy a full fledged notebook at the moment.

Thanks I didn't think so but was hoping or dreaming of making this old thing just a little faster.

Prices on small laptops have really come down lately. Something in the $300/350 range would be much faster than what you have

Netbooks are ideal for light works like surfing.
They are not too expensive either.
